Application of stainless steel pipe in the fire pipeline system

The fire pipeline includes two systems: a fire hydrant system and a water sprinkler system.

The stainless steel fire-fighting piping system is a fixed fire-fighting facility widely used in China. Nowadays, the fire water supply pipes in the water sprinkler system use 304 stainless steel pipes. As we all know, the service life of stainless steel pipes is relatively long, which can reach 100 years, and the shortest is at least 70 years, which is as long as the life of buildings. Furthermore, the most prominent corrosion resistance among many pipes is stainless steel pipe, because stainless steel will passivate with oxidant, and a protective film will be formed on the surface of stainless steel, which can prevent the further occurrence of the oxidation reaction. In addition, stainless steel can be recycled without causing environmental pollution, so stainless steel waste also has great economic value.

The tensile strength of 304 stainless steel pipe is very high, which is 2 times that of steel pipe and 8 to 10 times that of plastic pipe, and has good ductility and toughness, so 304 stainless steel pipe can well withstand vibration impact and thermal expansion and contraction. No water leakage, no explosion, fireproof and shockproof, very safe and reliable. 304 stainless steel pipe can be processed by cutting, forming, and welding and the processing difficulty is very low.
